2. This occurs when the appliance certificate is issued to a short name instead of the fully qualified domain name (FQDN).
Follow the steps below to fix this issue -
1. Access the appliance via SSH and update the hostname to FQDN if it is currently a short name or does not match the DNS host record.
A. For appliance versions 8.8 and above, follow the instructions in Photon Network Manager Commands to update Hostname/IP Address/DNS in SRM & vSphere replication (312686)
B. Refer to the instructions below for appliance versions 8.7 and earlier
